Taking on the High Moutains
The Switzerland of Catalonia
As I look back on all the places I’ve hiked, the Carros de Foc stands out as one of the most physically demanding experiences I’ve had—testing my endurance over several days in the high mountains.
On this particular day, I began with a peaceful stroll along the banks of Estany Negre, heading toward Refugi Ventosa i Calvell. Light rain came and went, but the weather remained beautiful overall. I moved slowly, like a turtle, savoring the unfolding landscape and stopping often to take it all in. The rhythmic sound of cowbells echoed through the valley as herds made their way home for the evening.
Eventually, I realized the sun was beginning to set and darkness was approaching. I picked up my pace, hoping to reach the refuge in time for dinner. When I arrived, the hut seemed quiet from the outside—but inside, it was bustling with activity. The staff at reception quickly urged me to get settled, as dinner would be served soon.
I hurried upstairs to drop off my things at an available bunk and took a quick, cold shower. Back downstairs, I found a seat at one of the communal tables and struck up a conversation with a friendly hiker from Valencia. We had a great chat, and he even gave me an extra map, which turned out to be incredibly helpful.
That evening marked one of the many moments when I felt both humbled and grateful. I hadn’t expected Carros de Foc be so physically challenging—especially in my current condition—but the beauty, solitude, and camaraderie made it an unforgettable adventure.
Carros de Foc (meaning "Chariots of Fire") started as a challenge among mountain refuge keepers in the 1980s, who decided to visit each other in a single journey. Over time, it became an official trekking circuit, attracting hikers from around the world.
Carros de Foc is a legendary high-altitude trekking route in the Aigüestortes i Estany de Sant Maurici National Park, located in the Pyrenees of Catalonia, Spain. It connects nine mountain refuges, forming a circular route through stunning landscapes of jagged peaks, crystal-clear lakes, and lush valleys.
The Route
The circuit covers around 55-65 km with 4,800+ meters of accumulated elevation gain, making it a challenging but rewarding trek.
It can be completed in 5 to 7 days, depending on pace and conditions.
The route crosses diverse alpine terrains, with elevations ranging between 1,900 and 2,800 meters.
Highlights
Estany de Sant Maurici – One of the most iconic glacial lakes in the Pyrenees, dominated by the striking Els Encantats peaks.
Colomers Cirque – A dramatic cluster of glacial lakes surrounded by granite peaks.
Monestero Valley – A wild and remote area with waterfalls and untouched nature.
Portarró d'Espot (2,430m) – A high mountain pass offering breathtaking panoramic views.

Experience
Season: The best time to hike is June to September, when the snow has melted, and refuges are open.
Difficulty: Moderate to difficult, requiring good physical condition due to the elevation changes and long distances.
Wildlife: Expect to see Pyrenean chamois (isards), marmots, golden eagles, and vultures.
Weather: Highly variable—clear skies can turn into storms quickly, so proper gear is essential. It’s a priceless experience and I don’t know if I could do it again. I must say, it is still possible. It was just Yes, you get to meet wonderful group of people. . Talking about challenging trails in one setting and that’s the one in Catalonia and at the borderline of Aragón had tested my endurance in terms of trekking.
